Embodiment Construction

[0018] The following instructions describe techniques for suspending thread execution in a multithreaded processor. In the following description, numerous specific details are given to provide a fuller understanding of the present invention, such as logic implementations, opcodes, means for specifying operands, resource partitioning / sharing / duplication implementations, types and interrelationships of system elements, And the choice of logical partitioning / integration. However, one skilled in the art will recognize that the present invention may be practiced without these specific details. In other instances, control structures, gate level circuits and full software instruction sequences have not been shown in detail in order not to obscure the invention. Those of ordinary skill in the art, reading the included description, will be able to perform the appropriate function without undue experimentation.

[0019] The disclosed techniques may allow a programmer to implement a su...

Abstract

Techniques for suspending execution of a thread in a multi-threaded processor. In one embodiment, a processor includes resources that can be partitioned between multiple threads. Processor logic receives an instruction in a first thread of execution, and, in response to that instruction, relinquishes portions of the portioned resources for use by other threads.
